Conveyor belt system with positional transformation of weight data |
摘要 |
A scale position compensation means for a conveyor belt material transport system, the system including a conveyor belt having a tail end and a discharge end, belt drive means, and a weight signal generating means. Belt travel signal generating means produce a belt travel signal representing the change of belt position. The weight signal generating means produce a first digital weight signal representing a weight of material associated with a portion of the belt adjacent to a first reference point located between the tail and discharge ends. The scale position compensation means are responsive to the first digital weight signal and the belt travel signal to produce a second digital weight signal representing a weight of material associated with the abovementioned portion of the belt when it is adjacent to a second reference point located between the first reference point and the discharge end. The compensation means comprise a memory for storing the first digital weight signal for a time interval having a duration related to the rate of change of belt position and to the distance between the first and second reference points.
